An SRV record, which is short for Service record, is a DNS entry employed to outline the servers which run a specific service for a domain name. Quite simply, you’ll be able to use your domain not just for a site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have an Internet site with it. Whenever you set up the SRV record, you may choose what IP it'll employ, on which port the connection to the specific server is going to be established along with the priority and the weight of the record assuming that you have several SRV records for the very same service. The latter option allows you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for a variety of purposes and even with different providers in case the same one is not able to provide all services you need.
